Hi Scotty, greetings from downunder.
My 2010 Camry 2.4 auto 110k miles has engine & traction control lights on, code P0136 O2 Sensor Circuit Bank 1 Sensor 2, short fuel trim 1.6 (0.8-2.3) long fuel trim -7.7 (-7.7-7.7), car runs fine.
Should I replace or clean O2 sensor or do something else?
PS Please give Lucy a pat for me.
Love your show
Kind regards, Dave
Forget the cleaning O2 sensors. Check this link for more info:

And if you decided to change the sensor, get an OEM.
